Get It Right Before You Grill: The Crucial First Step

Buying a new grill is exciting—but before you fire up your first burger or steak, there’s one critical step many people skip: seasoning your grill. Much like seasoning a cast iron skillet, this process prepares your grill for real-world use by burning off contaminants, laying down a protective layer, and building the foundation for clean, flavorful cooking. Whether you’re using a gas grill, charcoal unit, or hybrid model, proper seasoning is the key to extending lifespan, improving performance, and delivering unbeatable flavor from the start.

Why You Should Always Season Your Grill

Even top-tier grills like those from Napoleon, Weber, or Primo come with coatings, residues, and machine oils that you don’t want mixing with your food. Seasoning your grill is more than a one-time chore—it’s an investment in better cooking. Here’s what you gain:

Burns Off Residues: Removes grease, oil, and dust from manufacturing and packaging.
Prevents Rust: Oils create a protective barrier that wards off rust and corrosion.
Improves Flavor: A seasoned grill adds subtle smoky flavors and prevents metallic tastes.
Easier Cleanup: Food is less likely to stick to oiled, polymerized grates.
Boosts Lifespan: Protects the entire cooking surface from weather and wear.

Skipping this step can lead to early rust, bad-tasting food, and a frustrating start to your BBQ season. If you’ve spent good money on a grill, make sure it’s prepped to perform.

What You Need to Season a Grill

Before you begin, gather the right tools. You likely already have most of them at home:

High-temp neutral oil (canola, avocado, peanut)
Paper towels or lint-free cloth
Spray bottle (optional, for applying oil)
Grill brush or scraper
Protective gloves
Fuel (propane, charcoal, or pellets depending on your grill)

Pro Tip: Shop seasoning sprays, gloves, and accessories at DDR BBQ Supply to make this setup even easier.

Step-by-Step: How to Season Your Grill

Step 1: Clean the Cooking Grates

Start with clean grates. Use a grill brush to remove any dust or debris from shipping. If your grill was previously used, scrub off old grease and food bits before seasoning again.

Step 2: Apply a Light Coating of Oil

Use a paper towel or cloth to apply a thin coat of high-heat oil to the grates, burner shields, and interior walls. Don’t drench—just enough to lightly coat the metal.

Step 3: Preheat the Grill

Turn on your grill and set it to medium-high heat (350°F–400°F). For charcoal grills, light your coals and spread them evenly under the grates. Close the lid and let it run for 30–60 minutes.

Step 4: Let the Oil Bake In

The oil will polymerize—this means it bonds to the metal and forms a protective layer. You’ll notice the grates darken slightly and take on a golden, seasoned appearance.

Step 5: Cool and Inspect

After an hour, turn off your grill and let it cool. Once cooled, you can wipe away any excess oil. Your grill is now ready for its first cook!

Best Oils for Grill Seasoning

Oil	Smoke Point	Flavor Profile
Canola Oil	400°F	Neutral
Avocado Oil	520°F	Neutral
Peanut Oil	450°F	Nutty (avoid if allergic)
Grapeseed Oil	420°F	Neutral
Vegetable Spray	400°F	Neutral
Olive Oil	325°F	Not recommended—low smoke point

How to Season Different Grill Types

Gas Grills

Preheat all burners to high for 10 minutes
Apply oil to grates using a long-handled brush or cloth
Close lid and run at 350°F for 45 minutes

Charcoal Grills

Spread hot coals evenly under the grates
Apply oil before and after heating
Let run with lid closed for about 60 minutes

Hybrid or Multi-Fuel Grills

Follow instructions for your dominant fuel (gas or charcoal)
Focus on seasoning all metal parts regardless of fuel zone
Be thorough—hybrids often have more surface area to coat

Aftercare and Long-Term Maintenance

Re-Season Regularly: Re-season every few months or after a deep clean.
Keep It Covered: Invest in a quality cover to protect against weather.
Clean Grates After Each Cook: Brush while still warm to prevent buildup.
Empty Ash (Charcoal Grills): Moist ash can corrode metal quickly.

Expert Tips for Better Seasoning Results

Oil your grill after each use to extend seasoning lifespan.
Use long tongs or heat-proof gloves to avoid burns during oiling.
Consider re-oiling before long storage periods (like winter).
Avoid non-stick sprays with additives—they can create sticky buildup.

Common Mistakes to Avoid

Using too much oil: This can cause flare-ups and sticky grates.
Seasoning with the wrong oil: Low-smoke-point oils like olive oil will burn and create bad smells.
Skipping seasoning altogether: This shortcut often leads to rust, food sticking, and poor taste.
Underheating: Without proper heat, oil won’t polymerize correctly.

FAQs

Do I have to season a brand-new grill?

Yes. New grills often have residue from manufacturing. Seasoning is critical for safety, taste, and performance.

How often should I re-season my grill?

Every 2–3 months is ideal, especially if you cook frequently or clean the grates thoroughly. Re-season any time the grates look dry or develop rust.

Can I season my grill with bacon grease or lard?

No. Animal fats can go rancid and attract pests. Stick with vegetable-based, neutral oils.

What happens if I skip seasoning?

You might experience metallic flavors, sticking issues, or rust within a few weeks. Food will be harder to manage and grates can deteriorate faster.

Can I season my grill indoors?

No. Always season your grill in a well-ventilated outdoor space. The smoke and fumes from burn-off aren’t safe indoors.

Conclusion: Set the Stage for BBQ Success

Seasoning your grill isn’t just a chore—it’s a foundational ritual for every pitmaster and backyard griller. Whether you’re breaking in a brand-new unit or restoring a trusted favorite, this simple but essential process pays off with better performance, cleaner flavors, and a longer-lasting grill. It’s about taking ownership of your cook space from day one and setting yourself up for consistent, stress-free grilling. So before you throw on that first rack of ribs or sear your first steak, take the time to season your grill right. Your food—and your grill—will thank you.
